dyskinesia
Abnormal involuntary movements resulting from neurological dysfunction or medication side effects.
Full Definition
Dyskinesia encompasses a range of abnormal involuntary movements including chorea, dystonia, and tics, often arising as complications of neurological disorders or as side effects of medications, particularly dopaminergic treatments for Parkinson's disease. The term is crucial in movement disorder documentation and clinical trials. Editors must be precise about subtypes and distinguish dyskinesia from other movement abnormalities. The condition significantly impacts quality of life measures in neurological research and requires careful documentation of severity scales.
Usage
Usage note: Often occurs as a medication side effect; distinguish from primary movement disorders.
